A man throws a ball from one end of a ship on its deck. The ship is moving with uniform velocity. The trajectory of that ball is seen by a boy on the deck and another boy on the ground. Then they will observe :
1) Equal vertical heights and different horizontal range
2) Equal vert Height equal horiz range
3) Equal time of flt and equal horiz range
4) Equal time of flt and diff vertical heights
